An ND: yag laser (Neodymium-doped Yttrium Aluminum Garnet laser) is a type of laser that emits light at a wavelength of 1064 nm. It is commonly used in medical and cosmetic procedures because it penetrates deeply into the skin, making it effective for treating various skin conditions and for laser hair removal.

Here are some of its key applications:

1. Tattoo Removal: The NDlaser breaks down ink particles in tattoos, allowing the body to naturally absorb and remove them.
2. Hair Removal: The laser can target hair follicles, slowing hair growth and providing long-term reduction.
3. Vascular Lesions: It can treat spider veins and other vascular issues by targeting the blood vessels.
4. Skin Rejuvenation: It helps reduce fine lines, wrinkles, and hyperpigmentation.
5. Acne Scar Treatment: NDlaser can help reduce acne scars by stimulating collagen production.

The wavelength can be adjusted to treat different skin types and conditions effectively.
